3.2.4 Power supplies
3.2.4.1 NOTE
Any differential switches placed to protect drives shall have type B intervention characteristics (in accordance with the second amend-
ment to IEC 755).
3.2.4.2 SERVICES
Power supply: single-phase 230Va.c. ±10 % – 500mA max. (terminals: 230V)
Minimum section of connecting cables: 1,5 mm²
Protect the supply with no.2 delayed fuses with a rated current 1A.
3.2.4.3 POWER
The power supply of the
PWM3D-000 drive can
be supplied in the following ways:
•
A three-phase ground neutral network with a chained voltage within the limits indicated on the drive plate (see
"Identification plate on page 5. Insert between the three-phase network and the drive a three-phase inductance of at least 100
uH sized for the current absorbed by the drive and having a saturation current equal to at least twice the rated current (see
Drawing 1 on page 11.
•
From a transformer with connections
/
and centre star on the ground or a self-transformer (
/
) to adapt the mains
voltage.
•
From a D.C. line (see Drawing 2 to page 12.
•
Only for the drive Size 1
: From a single-phase network with voltage within the limits indicated on the drive plate (see
"Identification plate“ on page 5). Insert between the single-phase network and the drive an inductance of at least 100 uH
sized for the current absorbed by the drive and having a saturation current of at least twice the rated current (see Drawing 1
on page 11).
The power supply of the
PWM3D-010 drive
can only be supplied in the following way:
•
From a D.C. line (see Drawing 2 to page 12).
Always protect your feeding with ultra-fast fuses as shown in table 2 on page 7.
